Analysis of the Carrying Capacity of the Pile Foundation in the Switchyard Construction Project in the Pangkalan Susu - North Sumatra PLTU Area

Introduction

The pile foundation is a crucial component of construction projects, serving as a vital link between the structure and the soil beneath. In the Switchyard construction project in Pangkalan Susu PLTU, North Sumatra, the analysis of the carrying capacity of the pile foundation was conducted to ensure that the structure built could withstand various loads and stresses safely. This process involves several methods of investigation and calculation to determine the carrying capacity of piles.

Methods of Calculating the Carrying Capacity of Pile Foundations

There are various methods that can be used to calculate the carrying capacity of pile foundations, including:

  • Sondir Test: This method involves using a sondir tool to measure the resistance of the soil to penetration.
  • Standard Penetration Test (SPT): This method involves driving a standard sampler into the soil to measure the resistance to penetration.
  • Calendaring: This method involves using a calendaring tool to measure the resistance of the soil to deformation.
  • Loading Test: This method involves applying a load to the pile to measure its carrying capacity.

Each of these methods has a different way of calculation, resulting in a variety of capacity values. This study aims to calculate the carrying capacity of the pile from the test results and compare the results for a single pile.

Results of the Calculation

Based on the data obtained, the calculation of pile capacity shows a significant difference between various methods. For example:

  • Sondir Data: The Aoki and De Alencar method produces a carrying capacity of 115,640 tons, while the Meyerhof method shows a much higher number, which is 280,339 tons.
  • SPT Data: Using the Meyerhof method produced a carrying capacity of 198,287 tons, while the Danish Formula obtained 123,337 tons and the Modified New ENR produced 133,131 tons.
  • Loading Test Results: The Davisson method records the carrying capacity of 124.0 tons, while the Mazurkiewicz method shows the highest number, which is 216.0 tons.

Importance of Selecting Appropriate Methods

In the context of development projects, the selection of appropriate methods to calculate the carrying capacity of the foundation is very important. Using more accurate data from the loading test is a safer step to ensure sustainability and structure safety. Therefore, the results of this analysis indicate that in construction projects, it is essential to consider the results of various test methods and select the most suitable for soil conditions and the burden to be borne by the structure.

Conclusion

This research not only provides an overview of the carrying capacity of the foundation of piles in the Pangkalan Susu PLTU area but also emphasizes the importance of the selection of appropriate testing methods to produce accurate and trustworthy data in development projects. This analysis can be a reference for engineers and other related parties in making decisions regarding the design and construction of a safe and efficient foundation.
